Simply put, the malleability of a compound will determine the bond. Metallic bonds are very malleable, while ionic bonds are very brittle.
Answer:
120 moles of Mg
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
3Mg + 2H₃PO₄ —> Mg₃(PO₄)₂ + 3H₂
From the balanced equation above,
3 moles of Mg reacted to produce 3 moles of H₂.
Finally, we shall determine the number of mole of Mg needed to produce 120 moles of H₂. This can be obtained as follow:
From the balanced equation above,
3 moles of Mg reacted to produce 3 moles of H₂.
Therefore, 120 moles of Mg will also react to produce 120 moles of H₂.
Thus, 120 moles of Mg is needed for the reaction.
Answer:
30 moles of CO₂
Explanation:
balanced equation ,
CS₂+3O₂ → CO₂+2SO₂
From equation, 3 moles of O₂ are needed to make 1 mol of CO₂.
This means to produce 1 mol of CO₂, we need 3 moles of O₂, then how many moles of CO₂ will be produced from 90 moles of O₂ ?
Use unitary method to solve such problems,
Number of moles of CO₂ that will be produced:
= 
=
= 30 moles of CO₂
The answer is c.
Elements on the left side of the table are metals, such as sodium, lithium, potassium, etc.
Elements on the right side are non metals, such as Chlorine, Fluorine, Bromine, etc.
